Flat panel solar water heater does not go into the water after a while

There are several possibilities:

1. In addition to the possible reasons for the leakage of the water tank and the dissatisfaction with the water supply that you have ruled out, I think you should check whether the mixing valve has a leakage problem?

2. Is this an accidental phenomenon or a frequent occurrence? If it happens to happen, it means that you are taking a bath late, the tap water has been stopped, or the tap water pressure happens to be very low, or the tap water maintenance is out of supply, so it causes the hot water diversion of the mixing valve - part of the hot water flows through the cold water inlet and enters the tap water network.

3. If it occurs frequently, it means that you live on the fifth floor, and the tap water pressure has been unstable, up and down. Catch up with the hot water diversion when the bath is low. If the neighbor turns on the faucet, the hot water will come out.

4. Improvement method: add a one-way valve on the tap water pipeline, only cold water needs to enter, and hot water is not allowed to flow back.

There's limescale in there, and that's what I do, and there's a filter in the pipe or faucet, just wash it.

Looking at the problem you mentioned, I personally feel that it is caused by low water pressure and too slow hydration. The float valve is set in the water tank to control the automatic water replenishment, and when the water level drops, the water replenishment function will be automatically turned on, and the water will be replenished while using water to keep the liquid level in the water tank at a certain height. After a day of sunshine, the water temperature in the tank will be relatively high, and although the water temperature will decrease after mixing the water, the general temperature can still meet the bathing needs, so you say that you can generally reach 4-5 people to bathe, but due to the low water pressure, slow water replenishment, the liquid level in the water tank drops when the water is too fast, and the water pump will not be turned on when it is lower than the lowest liquid level, so there is no hot water down as you say, and after a night of replenishment, the liquid level returns to normal, so you can take a normal bath the next day.

Pure hand fighting, hope!

Generally no problem, it won't burn out

If it is a regular household water heater, there is still water in the water heater even if the water is stopped.

It's just that because the barrel is airtight, there is no water pressure after the water stops, so the water cannot be released at the water outlet, and it feels like there is no water in the barrel.

Moreover, the control system has the function of preventing dry burning, so it will not be affected.

Solar water heaters

Solar water heater is a heating device that converts sunlight energy into heat energy, heating water from low temperature to high temperature to meet the use of hot water in people's life and production.

Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters according to their structural form, mainly vacuum tube solar water heaters, accounting for 95% of the domestic market share.

Vacuum tube household solar water heater is composed of heat collector tube, water storage tank and bracket and other related spare parts, the conversion of solar energy into heat energy mainly relies on vacuum collector tube, vacuum collector tube uses the principle of hot water floating and cold water sinking, so that the water produces microcirculation and obtains the required hot water.

Friend, if the water is cut off for a long time, and the sun is strong, when there is no water in the solar water storage tank, the lighting panels will be burned out. Friends, except in winter, you must ensure that there is a certain amount of water in the water storage tank to ensure the safety of the lighting panel.

It depends on whether your home control system has the function of preventing dry burning, if so, it will not have an impact, or you can directly cut off the power supply of the electric heating and controller. However, it is recommended that you close the sluice gate after the solar water heater is fully watered, if the product is empty for a long time, it will greatly reduce the life and use effect of the product.

The solar energy of the glass tube will burn dry, and the solar energy of the flat plate will not burn out. There is no effect on solar energy.

I used to make solar water heaters, this kind of problem is often encountered, first, you need to fill the water, and then turn off the solar main valve (turning off the main valve can be 100% safe, if not turned off there may be an accident and water channeling). All power sources for solar energy are withdrawn. After these three steps, it's basically the same.

Of course, if you want to be more secure, get a sunscreen net upstairs and cover the solar cover, so you can go out for a few months without a problem.

Fill the solar water heater with water and turn off the sluice.

Solar water heaters

After the water is emptied, it can not be put on the water again, check:

1. Determine whether there is water in the water pipe;

2. Make sure that the hot water valve of the solar energy has been opened;

3. Confirm whether the solenoid valve has been opened;

4. Determine whether the solar controller can power up the solenoid valve (12V);

After the above four possible problems are eliminated, it is impossible for the solar water tank to be free from water.

Summary. The solar water heater no longer produces hot water after the water is stopped1First of all, make sure that there is no problem with the water supply.

Clear the filter, check the water valve, and then unload the solar water pipe from the solar energy, add water, see that there is no water, if the water does not come out, it means that the pipeline is not good, if the water comes out, clean up the solar energy water inlet and outlet and overflow port, exhaust port, to see if there is any blockage. 2.If there is no problem, and the water does not come out, you can only pull out a vacuum tube, then add water, rinse more, and there should be no problem.

2.If there is no problem, and the water does not come out, you can only pull out a vacuum tube, then add water, rinse more, and there should be no problem.

Friends, I really don't understand, you can be more specific.

It felt like there was no water in the bucket. If you have to release water, open the inlet and water will flow out of the outlet...

1. Reason: The user has not cleaned the dust on the collector (or vacuum tube) of the solar water heater for a long time, which affects the heat collection capacity of the collector plate (or vacuum tube), resulting in the solar water heater not being able to put hot water.

Solution: Wipe the dust on the collector (or vacuum tube) regularly to ensure the normal heating performance of the solar water heater.

2. Reason: Water leakage in the water tank or hot and cold water interface of the solar water heater.

Solution: Ask special maintenance personnel to test and repair in time.

3. Reason: The tap water pressure is too low or too high.

Solution: Balance the water pressure, if the tap water pressure is too high, it can be solved by reducing the tap water flow; If the tap water pressure is too low for a long time, it is necessary to install a booster pump to increase the tap water pressure.

If it is not possible to put the water in the last two days, the reason is that the temperature is too low and the pipeline is frozen. Now, if your home solar is equipped with an electric heating belt (heat tracing), you can activate the electric heating belt, and it will melt in a while. If not, you'll have to wait for the weather to get warmer.

Choose a solar water heater or choose a water heater with good quality, Huangming's quality is leading in the world.

There are two situations: 1. The current temperature is too high, and the pipeline may have a gentle slope causing air blockage; Take water supply to remove pipeline gas;

2. Due to the cold weather, the pipeline is passive, start the thawing belt for 3-5 minutes, and turn on the hot water faucet at the same time, and the hot water can flow out when the ice melts.

3. The Four Seasons Muge water heater adopts fully automatic operation, no manual guarding, reliable quality, low quality and low price, trustworthy!

It should be that the pipeline is frozen and blocked, or there is a broken valve in the room.

If the pipe is frozen, start the electric tropic thawing.

Turn on the water inlet switch to water the water tank.

Good afternoon, dear, I'm honored to answer for you. If the solar flat panel water heater does not get water, there may be several reasons:1

Water source problems: Check whether the water source valve is open, whether the faucet is operating properly, and whether the water source pipe is damaged. 2.

Clogged water pipes: Check if the water inlet pipes are blocked. Pliers or other tools can be used to remove wild debris from the pipes.

3.Valve problem: Check whether the valve in and out of the water pipe is open, whether there is looseness, damage, etc.

4.Air pressure problem: Check if there is insufficient air pressure to prevent water from entering, and check whether the water pump is working properly.

5.Pipeline leakage: Check whether there is water leakage in the water pipe, especially at the joint, and repair the leakage in time.

It needs to be inspected and repaired on a case-by-case basis, and if you can't solve the problem yourself, it is advisable to seek help from a professional. At the same time, for the use and maintenance of the solar panel water heater, it is recommended to clean and maintain it regularly to ensure its normal operation and service life. I hope mine can help you

Summary. The reasons why the solar flat water heater does not enter the water are: 1. The vacuum tube is broken

If the solar water heater is not used properly, it is easy to cause the vacuum tube**, resulting in all the water flowing out of the broken vacuum tube after the solar water heater is turned on. Most of the reasons for the vacuum tube are caused by the water supply to the solar water heater after the sun rises, because the temperature in the vacuum tube is already very high at this time, it can reach more than 200 degrees Celsius, and if the temperature is very low at this time, the cold water will be **. Therefore, the water supply of the solar water heater must be carried out before sunrise or 1 hour after sunset.

There are also a few reasons because the vacuum tube is frozen and cracked, if there is no sunlight for many days in the cold winter, the water in the vacuum tube also freezes, causing the vacuum tube to freeze and burst, so if there is no sun for several days in the winter, use up the water in the solar water heater as soon as possible. 2. The upper and lower water pipes of the solar water heater are frozen or leaking: because some of the upper and lower water pipes are outdoors, if the warmth measures are not done well, it is easy to make the water pipes frozen, and if the water pipes are frozen, the water will not be able to get on the water, so we should pay attention to the warmth of the water pipes.

There is also the situation of water pipe leakage, which may be frozen and cracked or the link head of the water pipe is loose, which will cause all the water to go up and leak out, resulting in the illusion that no water will enter the water. 3. Automatic controller: Because sometimes the control panel and sensor fail to transmit the wrong signal or cannot transmit the signal to the actuator, resulting in the inability to water supply.

At this time, the control panel and sensors should be replaced in time.

3. Automatic control instrument: Because sometimes the control of the base panel and sensor fails to transmit the wrong signal or cannot transmit the signal to the actuator, resulting in the inability to get on the water. At this time, Youpei should replace the control panel and sensors in time.

The water heater has not been cleaned for a long time, resulting in scale in the water heater, which has accumulated all year round and has not been cleaned, and the space for water in the water heater is getting smaller and smaller.
